Vedclass · Answer

(B) Human evolution is characterized by several key anatomical changes. Among the given options,the reduction in jaw size (prognathism) is a hallmark of human evolution. As the brain size increased significantly (encephalization),the facial structure became more orthognathic (flatter face),leading to a reduction in the size of the jaw and teeth compared to our primate ancestors. While other traits like the loss of the tail occurred earlier in the hominoid lineage,the reduction in jaw size is a defining trend specifically associated with the evolution of the genus $Homo$.
